Mol bio classics
The document summarizes the classic experiment conducted by Matthew Meselson and Frank Stahl in 1958 that determined the mechanism of DNA replication. They grew bacteria in a culture containing the heavy isotope nitrogen-15 to produce "heavy" DNA. When these bacteria were then grown in a culture with regular nitrogen-14, the resulting DNA had an intermediate density, indicating that DNA replicates semiconservatively, with each parent strand serving as a template to produce two daughter double helices. Subsequent experiments showed that after a second generation, the DNA was half heavy and half light, confirming the semiconservative model. This elegant experiment provided the first direct evidence that DNA replicates in this manner.

VESTIBULAR SYSTEM MASLP
The vestibular sensory organs of the inner ear responds to physical stimuli related to movement and orientation of the head in three-dimensional space. In response to mechanical forces acting on the inner ear, neural messages regarding head motion and position are generated by the vestibular apparatus and relayed to the brain. That information along with visual and proprioceptive input, is used by the central nervous system (CNS) to maintain clear vision during head movement, to control muscles responsible for upright posture and to provide a sense of orientation of the body with respect to the surrounding environment.
Although the vestibular system is one of our major sensory modalities, it differs somewhat from other senses such as vision and hearing in that it operates largely in the service of motor reflexes, outside the field of conscious perception. Thus we are not aware of vestibular sensory input unless the system is subjected to unusually high levels of stimulation or is compromised by disease, in which importance of vestibular function becomes acutely obvious. Some fundamental aspects of vestibular anatomy and physiology, emphasis on features of the system that provide the foundation for clinical testing of vestibular function.
History of immunology
Edward Jenner in 1798 discovered that exposure to cowpox provided protection against smallpox in humans, laying the foundation for vaccinations. Louis Pasteur further developed vaccines in the late 1800s by using weakened versions of pathogens to provide immunity. In the early 1900s, scientists such as Metchnikoff and von Behring discovered the cellular and humoral components of the immune system, including phagocytic cells and antibodies. The modern field of immunology was established through breakthroughs including the identification of T and B cells in the 1950s and the discovery that antibodies target specific antigens. Recent work in cancer immunotherapy has focused on inhibiting negative immune regulation to stimulate anti-tumor responses.

Building an efficient infrastructure, standards and data flow for metabolomics
Christoph Steinbeck from the European Bioinformatics Institute discusses developing efficient infrastructure, standards, and data flow for metabolomics. Metabolomics measures small molecule metabolites in organisms and generates large amounts of data. The MetaboLights database was created to share metabolomics data openly. It is growing rapidly with a doubling time of 3 months for metabolomics data. Efforts are underway to build standardized reference data through projects like COSMOS and MetabolomeXchange. While genomes of thousands of species have been sequenced, far fewer complete metabolomes exist. The talk advocates for focused efforts to map metabolites and build quantitative models of well-studied model organisms' metabolomes.

Evidences of evolution from patterns of development
The document provides evidence for evolution from patterns of development in organisms. It discusses several lines of evidence, including:
1) Homologous structures that have a common origin but different functions, such as the thorn of a plant and tendril, providing evidence of descent from a common ancestor.
2) Analogous structures that have a similar function but different origins, such as wings of insects and birds, indicating similar adaptations.
3) Vestigial structures that were functional in ancestors but no longer serve a purpose, found in both plants and animals including humans.
4) Embryological evidence from plant and animal embryos that show similarities in early stages, indicating common ancestry.
Modern gene concept
This document discusses different concepts of genes including classical concepts like alleles and modern concepts like jumping genes, overlapping genes, split genes, nested genes, and fusion genes. It then focuses on jumping genes or transposons, providing details on their discovery by Barbara McClintock in maize in the 1940s. Transposons are able to move from one location in the chromosome to another. The document discusses types of transposons like IS-elements, P-elements, and retrotransposons. It also discusses the significance of transposons and examples of transposon systems in maize like the Ac-Ds system.
Dicot embryo ..crucifer type
The document discusses the development of dicot embryos with a focus on plants of the crucifer type. It examines the early stages of embryo formation and growth within the seed, highlighting key developmental processes. The crucifer plants are used as an example to illustrate common dicot embryo development.
Transgenic plants for viral disease resistance
- More than 300 plant viruses have been reported which can cause diseases in crops like retarded growth, lowered yields, and even complete crop failure.
- Plants have natural defenses against viruses like hypersensitive response and extreme resistance which causes infected cells to die in order to prevent spread of the virus.
- Transgenic techniques can also be used to develop virus-resistant plants, such as inserting virus coat protein, replicase, or movement protein genes, using antisense RNA or RNA interference strategies.
- While transgenic virus-resistant crops could control plant virus diseases, there are some potential safety issues to consider like increased virulence of viruses, recombination between viral sequences, and effects on non-target organisms
Micropropagation
This document discusses micropropagation, which is the rapid vegetative propagation of plants using modern tissue culture methods to produce genetically identical copies. It can be used to multiply genetically modified plants, overcome limitations of conventional breeding, and provide sufficient plantlets from stock plants that do not produce seeds or respond well to other propagation. The key methods are multiplication through meristematic tissue, adventitious shoots, somatic embryogenesis, and organogenesis. Micropropagation has commercial uses and significance in producing disease-free plants year-round, exchanging germplasm internationally, conserving genetics, and producing synthetic seeds. While expensive, it provides uniformity and allows maintaining germplasm stocks for years.
Comparitive genome mapping and model systems
Comparative genome mapping involves comparing genetic maps between closely related species to study genome evolution and understand relationships at the genetic level. Genomes can be compared by looking at features like gene location and order, as well as sequence similarity. Many model systems have been used for comparative mapping, including plants like rice and maize, Arabidopsis and Brassica, tomato and potato. These studies have revealed things like conserved synteny between species, rates of rearrangement, and the effects of polyploidization. Comparative mapping is a useful tool for understanding genomes and their relationships across species.
Gene silencing and its significance
Gene silencing is a molecular process that down regulates gene expression at the transcriptional or translational level. It allows researchers to study essential genes and provides insight into disease development since many diseases are associated with reduced gene expression. Gene silencing occurs through various mechanisms including histone modification, DNA methylation, and small RNA pathways. It has applications in research areas like producing virus resistant plants and modifying food quality and plant traits.
Mechanism of drought tolerence in plants
Drought tolerance in plants involves three main mechanisms: morphological, physiological, and genetic/molecular. Morphological mechanisms include drought escape and avoidance strategies like early reproduction or reduced water loss through waxy leaves. Physiological mechanisms regulate water use and loss, like stomatal closure and osmotic adjustment. Genetic and molecular mechanisms change gene expression, upregulating genes that produce proteins protecting cells from stress and regulating hormone signaling and transcription factors that control stress response pathways. Together these overlapping mechanisms help plants adapt and survive periods of low water availability.
Purity test analysis
Physical purity analysis determines the proportion of pure seed, other seeds, and inert matter in a seed lot by weight. It is an important step in seed testing to ensure farmers receive seeds that are free from contamination and meet minimum quality standards. The analysis identifies various seed and inert components to improve plant stands, raise pure crops, and ensure proper seeding rates. It is conducted according to ISTA guidelines by separating a working sample into pure seeds, other seeds, and inert matter using tools like sieves, blowers, and microscopes to examine each component.
Tundra forest
The document provides information about the tundra biome. It describes the tundra as a vast, cold region characterized by treeless vegetation and permanently frozen subsoil. It exists in the northernmost regions of the world and at high elevations. Plants and animals in the tundra are adapted to harsh conditions like freezing temperatures, short growing seasons, and nutrient-poor soil. Examples are given of the specific locations and characteristics of the Arctic, Antarctic, and alpine tundra biomes.
Evidences of evolution from patterns of development
The document provides evidence for evolution from patterns of development in plants and animals. It discusses several lines of evidence including homologous and analogous structures, vestigial organs, fossils showing transitions in horse evolution, and similarities seen in early plant and animal embryos which indicate common ancestry. For example, it notes the wing of a bird and insect serve the same function but have different structures, showing analogous not homologous evolution. Together, these various developmental patterns found across species provide strong support for the theory of evolution.
History of embryology in plants
Plant embryology is the study of plant development from fertilization to the formation of a mature embryo. Key developments included the discovery of pollen tubes and their role in fertilization in the 17th-18th centuries. In the 19th century, scientists discovered that the embryo forms from the fertilized ovule rather than from the pollen tube tip. Double fertilization, where one sperm fuses with the egg and one with the central cells, was discovered in the late 19th century. The 20th century saw advances in microscopy techniques that improved understanding of embryogenesis. Indian scientists like Maheshwari and Johri made seminal contributions to angiosperm embryology in the 20th century. Modern plant embryology explains
Steroid transformation by fungi
This document discusses steroid transformation by fungi. It begins by defining steroids and their functions. Steroids are found naturally in plants, animals, and fungi. Several types of fungi can transform steroids, completing reactions like hydroxylation, oxidation, and other modifications. Fungal transformation of steroids is advantageous compared to chemical synthesis, as it uses aqueous conditions and is regioselective and stereoselective. The history of using fungi to transform steroids for drug production is described, highlighting its economic benefits. Methods of fungal steroid transformation and some examples of important transformations are summarized.

Syndromes caused due to algal toxins final
- Several types of harmful algal blooms produce toxins that can cause illness in humans through the consumption of contaminated shellfish or fish. These illnesses include Ciguatera Fish Poisoning, Diarrhetic Shellfish Poisoning, Neurotoxic Shellfish Poisoning, Paralytic Shellfish Poisoning, and Amnesic Shellfish Poisoning.
- The document outlines the causative organisms, toxins produced, mechanisms of action of the toxins, and symptoms in humans for each of these illnesses. Treatment involves managing symptoms, as there are generally no antidotes for the marine toxins. Prevention strategies include monitoring for algal blooms and providing public education.
Cell recognition and adhesion
Gap junctions allow direct communication between adjacent cells by forming channels between the cells' cytoplasm. The structure of a gap junction consists of connexons - cylinders of six transmembrane protein subunits called connexins - arranged back-to-back between the plasma membranes of adjacent cells. These connexons join to form channels about 1.5-2.0 nm in diameter that connect the cytoplasm of the two cells and allow small molecules and ions to pass directly between cells, enabling both electrical and metabolic cooperation.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
